Full Breakdown
Table 4-1 requires a 25-foot minimum front yard in the RR, R-7500, R-6000, SBR-6000 and MR-3200 districts alike. Rear yards run 25 feet in RR, 9 feet in R-7500, R-6000 and SBR-6000, and 20 feet in MR-3200. Side yards run from a single 5-foot minimum in R-7500, R-6000 and SBR-6000 up to 10 feet in RR, with a combined two-side total of 10 to 12 feet where a total applies; street side yards on corner lots run 15 feet, though lots legally established before January 1, 1994 with less than 60 feet of width may reduce a street side yard to 12 feet.
A requires every part of a required yard to stay open and unobstructed from 30 inches above grade upward to the sky, except for specifically permitted obstructions. Yards existing before May 1, 2007 cannot be reduced below the ordinance's current minimums unless a nonconformity exception applies. E lists what is allowed inside a required yard anyway: sidewalks, driveways, mailboxes, plantings, retaining walls up to six feet, chimneys projecting up to three feet, cornices and eaves up to five feet (staying two feet off the property line), and screened at-grade patios or decks that may extend up to eight feet into a front yard or anywhere in a side or rear yard. D.
Violations & Fines
Placing a structure or an obstruction not on the Section 4.14.4.E exemption list inside a required front, side or rear yard is a zoning violation enforced by the Brunswick County Planning Department, which can require removal of the encroachment or denial of a certificate of occupancy until the property owner obtains a variance from the Board of Adjustment. Permanent accessory structures must independently meet the setback standards in UDO Section 5.4.
